Definitions

  • the invention relates to a device for preventing the measurement of gaseous admixtures when dispensing liquids from a first into a second container via a delivery line in which a shut-off valve and a flow meter are arranged and to which a pressure measuring device is connected in front of the flow meter, the Output signal of the geodetic inlet height above the pressure measuring point is proportional and is applied to a valve to interrupt the dispensing of the liquid when the measured pressure falls below a first pressure value.
  • a suction break in the manner described is only suitable for delivery systems that work with gravity delivery. If a feed pump is used, suction breakage is naturally not possible.
  • Controlling the dispensing with the aid of a suction break has several disadvantages. This can lead to a negative pressure in front of the flow meter if the geodetic inlet height and the speed pressure height of the liquid do not cover the pressure loss in the pipe and fitting system. Furthermore, the suction refraction must take place very vigorously in order to achieve a sufficiently rapid reduction in the delivery speed even if the delivery line runs unfavorably behind the volume counter. Because of the reaction times to be taken into account, a suction break quickly leads to an oversteer with an associated undesirably strong reduction in the delivery speed. The subsequent elimination of the suction refraction is slow because of the low geodetic inlet height that is then only available. As a result, the delivery rate increases only slowly, since the air in the discharge line from the meter to the receiving container is only carried away to a limited extent due to the low liquid velocity, and the desired suction does not build up again or only very slowly.
  • the known degassing devices are also relatively complex and thus increase the effort for the entire measuring system. Furthermore, the output is limited by the design of a degassing device. With regard to the output, the degassing device is naturally the weakest link in the entire delivery system.
  • the invention has for its object to provide a device for preventing the measurement of gaseous admixtures when dispensing liquids, which has particularly low measurement errors in the wake and causes minimal effort.
  • shut-off valve is arranged behind the flow meter and its effective cross-section can be regulated and the output signal of the pressure measuring device is given to an actuating device for the shut-off valve which, from a second pressure value above the first pressure value, the flow through the shut-off valve throttles as the pressure decreases.
  • a conventional degassing device is dispensed with and instead is prevented from the outset that gaseous admixtures reach the volume counter to a decisive extent. This is based on the knowledge that as long as there is sufficient positive pressure in front of the flow meter, the proportion of gaseous admixtures is below the permissible limits. If the pressure drops in front of the flow meter, for example due to the decrease in the geodetic inflow level when emptying a container to be emptied, this provides an indicator that the proportion of gaseous admixtures is increasing. If the pressure in front of the volume counter falls below the second pressure value in the device according to the invention, this leads to a throttling of the shut-off valve a corresponding reduction in output.
  • the liquid in the container to be emptied is calmed down (avoiding turbulence due to eddy formation) and the geodetic inlet height can rise again as long as there is no complete emptying.
  • An increase in the geodetic inlet height causes a further increase in pressure in front of the flow meter, so that the shut-off valve can be opened again in order to temporarily increase the output. If the pressure in front of the flow meter falls below the first low pressure value, the shut-off valve is closed completely.
  • the lower pressure value can be exceeded again in the sense of an increase in pressure, so that the shut-off valve can open again with a limited cross section in order to cause the rest to slowly run down until the low first positive pressure value reached for the last time and is then not exceeded.
  • a device operating according to the invention has far smaller error tolerances than conventional devices, in particular those with degassing devices. Despite the achievable high measurement accuracy, the weight and size of the device according to the invention are lower than in conventional devices, so that, for. B. in tankers the payload is increased accordingly. Another advantage of the device according to the invention is that it causes a minimal pressure loss in the delivery line, so that the delivery rate ultimately depends only on the design of the line systems and the fittings. Compared to conventional dispensing devices, an increased dispensing performance can therefore be achieved with the aid of the invention.
  • the device according to the invention can be used for all possible delivery systems, regardless of whether they work with gravity or with feed pumps.
  • the device according to the invention can also be used equally in systems which optionally provide both pump and gravity delivery, both with empty hose and with full hose delivery.
  • the invention can also easily take into account the so-called gas pendulum process, in which there is variable pressure in the gas phase of the container to be emptied.
  • the shut-off valve is throttled in an advantageous manner according to a progressive characteristic curve.
  • the cross section of the shut-off valve is not changed in proportion to the change in pressure upstream of the flow meter, but in a progressive manner, i. H. initially relatively slowly with falling pressure and then steadily increasing disproportionately.
  • the first pressure value is advantageously above atmospheric pressure.
  • the measurement of atmospheric pressure in the area of the measuring device in front of the flow meter would mean that the line is already empty at this point. If the shut-off valve were only shut off completely at this point, it would be too late to avoid measuring gaseous admixtures.
  • the first pressure value should be greater than the pressure in the gas phase of the container to be emptied in order to avoid effects of the gas phase pressure with regard to the admixture of gas liquid.
  • the measuring point for measuring the pressure by the pressure measuring device can be either on the entry side or on the exit side of the quantity counter. In the case of the optional or exclusive use of a feed pump, however, the pressure measuring device measures the liquid pressure on the suction side of the pump.
  • the principle of the device according to the invention is based on the fact that the flow rate when dispensing liquids is reduced in accordance with the probability that gaseous admixtures are mixed in.
  • the pressure in the delivery line is used as an indication of the presence of gaseous admixtures.
  • the use of a shut-off valve to reduce the flow rate is advisable because shut-off valves are usually already prescribed by the authorities. It is also conceivable to make the delivery pump controllable in delivery systems working with delivery pumps and to have the regulating device regulate the delivery rate of the pump such that the delivery rate is reduced at an upper pressure value and the delivery rate becomes zero at a lower pressure value. Pumps of any type are known with which the flow rate can be made variable via the pump pressure, the pump speed or the cyclical delivery volume of the pump.
  • a two-stage shut-off valve can also be used as a shut-off valve. It is known per se in connection with delivery systems. It is controlled by quantity counters, which can be preset. When the set value is approached, the shut-off valve is adjusted to the smaller opening level so that it can be approached as precisely as possible to the precisely set end point.
  • a propeller pump of any pressure level can be arranged in the delivery line in front of the quantity counter, which is switched off when the shut-off valve begins to be throttled.
  • the propeller pump which is powered by a battery-powered electric motor, enables an increase when the petrol station is supplied Hung the speed of gravity, since the pressure level generated is sufficient to largely compensate for the resistances of the flow meter and the container to be filled.
  • the use of normal feed pumps with drive from the vehicle engine is not permitted when delivering petrol stations.
  • Figure 1 shows schematically a device designed according to the invention.
  • FIG. 2 shows a detail of the device according to FIG. 1 in a partially modified form.
  • a tank 10 for example a tank truck, has three chambers 11, 12 and 13.
  • the chambers 11 to 13 each have a drain opening, to which bottom valves 14, 15 and 16 are arranged directly.
  • the outputs of the bottom valves 14 to 16 lead to a manifold 17, from which a branch 18 via a feed pump 19, a flow meter 20, a shut-off valve 21, and a hose 22 leads to a tank 23 to be filled, for example an underground tank.
  • a pneumatic adjusting cylinder is assigned to each bottom valve 14 to 16, of which only one, which is designated by 24, is shown assigned to the bottom valve 14.
  • the actuating cylinders 24 are actuated with the aid of a control block 25, which is divided into three sub-units 26, 27 and 28, corresponding to the number of bottom valves.
  • Each sub-unit 26 to 28 is actuated by an adjustment button which has no reference number.
  • the control block 25 also includes a sub-unit 29 with an adjustment button, the output of which is connected via a throttle 30 to an input of a 2/3 directional control valve 31, the output of which leads to a pneumatic cylinder 32 for actuating the shut-off valve 21.
  • the adjusting piston of the valve 31 is spring-loaded by means of a spring 33.
  • the piston rod 34 engages on the underside of a membrane 35 which separates two pressure chambers 36 and 37 from one another.
  • the membrane 35 is provided by means of a spring 38. curious; excited.
  • the chamber 37 is connected to the atmosphere via a connection 39
  • the chamber 36 is connected to the interior of the branch line 18 via a pipe 40.
  • the opening 41 of the pipe 40 lies in the middle and in the lower region of the vertical section of the branch 18 and thus has the effect of a pitot tube, so that the pressure in the chamber 36 is a measure of the pressure in the region of the opening 41 in the pipe branch 18.
  • the pressure measuring point 41 is therefore on the suction side of the feed pump 19.
  • the control block 25 is supplied from the pressure medium source 42, a pressure medium line 43 initially being led via the subunit 29 and only then via a throttle 44 in series via the subunits 28, 27, 26.
  • the line 43 leads in at the output of the control block 25 via Throttle check valve 45 to a pulse valve 46, the output of which is connected via a line 47 to a further input of the subunit 29.
  • a storage volume 60 is connected to line 43 at the outlet of throttle check valve 45.
  • one of the bottom valves 14 to 16 must first be opened. This is initiated by pressing the associated adjustment button on the associated subunit. In the present case, for example, the subunit 26.
  • a pressure drop in the volume 60 arises behind the throttle and through the check valve 45 and accordingly on the spring-loaded side of the 2/2-way pulse valve 46 the second air connection via line 47 of the unit 29 is vented, and actuation of the unit 29 to open the shut-off valve 21 is possible, but does not yet lead to the shut-off valve 21 opening.
  • the shut-off valve 21 can be opened with the help of the pneumatic adjusting cylinder 32.
  • the same effect described occurs when another bottom valve is opened.
  • the shut-off valve interrupts delivery immediately, and restarting is only possible after the specified time. This can ensure a sufficient time for venting air inclusions in the line system below the tank 10 into the respectively open chamber.
  • this assumes that adequate ventilation from the manifold 17 is possible, i. H. that from the beginning of the measuring point there is a steady increase in the line, which, however, is always the case for tanker trucks for operational reasons.
  • the diaphragm 35 in connection with the spring 38 and the spring 33 acting on the piston (not shown) by the valve 31 are matched to one another in such a way that from a certain low positive pressure, indicated by the pressure h1 the diaphragm 35 adjusts the piston of the valve 31 via the piston rod 34 so that the pressure in the pneumatic cylinder 32 is reduced and thereby a Throttling the shut-off valve 21 brings about.
  • This throttling becomes progressively greater the lower the pressure at measuring point 41 is.
  • the shut-off valve 21 which is only partially open, closes quickly. After-flow quantities, in particular from the chamber walls, generally lead to a rise in the liquid level in the branch line 18 again after a short time, so that the shut-off valve is due to of the processes described again slowly opens with a very small cross section.
  • the shut-off valve 21 is actuated by a pneumatic adjusting cylinder 48, which has two cylinder chambers 49, 50 connected in series, each with a piston 51 and 52, respectively.
  • the piston 51 is biased downwards in the direction of the second piston 52 by means of a spring.
  • the piston 52 is freely movable in the cylinder 50 and its rod 54 is sealingly guided into the upper cylinder chamber 49.
  • the line coming from valve 31 is branched into lines 56, 57, each of which contains a spring-loaded throttle valve 58 and 59, respectively.
  • the outlet of the valve 59 leads to the lower cylinder chamber 50, while the outlet of the throttle valve 58 leads to the cylinder chamber 49.
  • the directional control valves 58, 59 are designed so that at full pressure in the line 55 both cylinder chambers 49 and 50 are pressurized, so that the shut-off valve 21 is adjusted to its fully open position. If the pressure in the line 55 drops, the pressure in the cylinder chamber 49 also drops, which leads to a corresponding throttling of the shut-off valve 21.
  • the pressure in the chamber 37 which in the exemplary embodiment described is equated with atmospheric pressure, can also be determined by the pressure in the gas phase in the chambers 11 to 13 (gas pendulum method) in order to have an effect of the pressure in the gas phase in the tank 10 to be emptied to prevent the admixture of gas in the liquid.
  • control device described can also be carried out twice if a two-stage shut-off valve 21 is used with a full opening stage and a reduced opening, so that both openings can be controlled as a function of the measured pressure in the branch line 18.
